点击共享图片打开URL

Question

我正在使用-FBSDKShareKit（4.40.0）：我想在Facebook上共享图像。 它应该可以轻按，并且应该像Endomondo应用程序一样打开网站。

我已经尝试过此代码，但是url包含照片，但它们不会显示：

    let sharePhoto = FBSDKSharePhoto()
    sharePhoto.image = someImage

    let content = FBSDKSharePhotoContent()
    content.photos = [sharePhoto];
    content.contentURL = URL(string: "https://facebook.com")!
    FBSDKShareDialog.show(from: self, with: content, delegate: nil)

他们是如何做到的？

Answer 1

使用它在Facebook上分享

导入社交

func shareToFb(_ yourImage:UIImage!)

    {
     let facebookURL = URL(string: "fb://")
      if (UIApplication.shared.canOpenURL(facebookURL!)) {
      let vc = SLComposeViewController(forServiceType:SLServiceTypeFacebook)
             vc?.add(yourImage)
                    vc?.setInitialText("Initial text here.")
                    self.present(vc!, animated: true, completion: nil)
                }
                else {
                    let urlStr = "https://itunes.apple.com/us/app/workplace-by-facebook/id944921229?mt=8"
                    if #available(iOS 10.0, *) {
                        UIApplication.shared.open(URL(string: urlStr)!, options: [:], completionHandler: nil)

                    } else {
                        UIApplication.shared.openURL(URL(string: urlStr)!)
                    }
                }


            }

看来@ 04FS是正确的。 这只是一个og：image。 他们将图片发送到服务器，然后生成带有html meta og标签的页面。 （之间存在重定向，因此对我而言这并不明显）
